Ratio Zero - the world’s first operational gear-based CVT. But before I get into how it works, let’s talk about why that matters. As you probably know, CVT stands for continuously variable ...

When it comes to serpentine belt tension, how your engine maintains it makes all the difference. Older engines often rely on a manual tensioner — a threaded bolt adjusted pulley that requires ...

Serpentine belt tensioners and pulleys aren’t the same thing, but they’re closely related, and while a pulley is its own individual part, a component of almost every tensioner is a pulley ...

Equilibrium deflections change reasonably with static span tension variation, but are more sensitive to variations of speed and longitudinal stiffness. The natural frequencies of the pulley-belt ...

Serpentine belts and timing belts are both key to keeping your engine running, but they also both perform very different purposes under the hood.

Your serpentine belt controls a number of components in your engine, so it's pretty important. Here are a few signs to watch out for if it starts to go.

There is a screeching noise from the pulley-belt in my 2015 Volkswagen Amarok. I have changed all the pulleys except the engine pulley. I have even changed the belt several times. It’s not going away.

Continuously variable radiuses between the belt position on the pulleys, as well as belt tension, are controlled electronically in conjunction with the engine’s electronics.
